Guy's and St Thomas' diabetes renal service

The Renal Outpatient Clinic based at Guy’s Hospital Diabetes and Endocrinology Day Centre provides care for patients with diabetes and renal (kidney) problems.

The service is operated by a multidisciplinary team consisting of a consultant in diabetes, a consultant in nephrology (kidney disease), a diabetes and renal specialist nurse, a dietician, and an anaemia nurse. Collectively, the team provides pharmacological treatment that aims to protect renal function, with access to research programmes and cutting-edge treatments, and has close links with Guy’s and St Thomas’ NHS Trust’s Renal and Dialysis Units.

Who Is the Service For?

The Renal Outpatient Clinic is for the following:


1. Anyone with stage 4 (GFR 15-29) or 5 (GFR < 15) kidney disease


2. Anyone with stage 3 (GFR 30-59) kidney disease and the following:

  • Rapid deterioration in renal function
  • Doubt about the cause of the kidney disease
  • Heavy proteinuria
  • Anaemia


3. Anyone on renal replacement therapy (continuous ambulatory peritoneal dialysis, haemodialysis, kidney/kidney-pancreas transplantation).


Anyone with stable stage 3 kidney disease should be referred to a general diabetes clinic.

Complications of diabetes

Complications of diabetes
Over time, diabetes can result in a number of complications which occur because of the effects of raised glucose levels on blood vessels.
